You know married couples where a woman has herpes and the man doesn't have sex and the man never gets herpes, right? It's not a given that just because you are having sex with someone with hsv that you will then have it too. She had safe sex with a condom. That doesn't mean zero risk but in general, that protected you and without any symptoms, you have nothing to become worried about. You also gave her oral, you don't have any hsv symptoms on your mouth, do you? So, I think that you can relax.
